Water fasting improve insulin and leptin sensitivity:


Insulin and lepton are important hormones that affect the body's metabolism. Insulin helps the  body store nutrients from the bloodstream, while leptin helps the body feel full.
Research shows that water fasting could make you  body more sensitive to leptin and insulin. Greater sensitivity makes thus hormones more effective.

for example, being more efficient at reducing blood sugar. Meanwhile, being more leptin sensitive could help your body process hunger signals more efficiently and, in turn, may lower your risk of obesity.
